Supermoto Rim Hub Conversion?
 

I just got what I thought would fit the CRF 250L supermoto rim set for my Templar. Turns out the inside diameter for the bearings is about half the size of the Tenplar that has the more standard size axle bolt diameter. My question is if I buy Tenplar hubs can I switch them out so I can use thease rims? Could I use the spokes that came on here or would I need different length spokes...?

If I can't make them work with just changing out the hubs I might return them and then just get supermoto tires for the stock rims and try and squeeze them onto the skinner rims.

I think i would see if you could swap out your Wheel bearings, if i am understanding the problem . you can measure what you need and search bearings by size also .

Any luck on figuring a solution out? I've researched the orion rxb250l supermoto wheels and they seem to be able to fit after pressing new bearings in of the new OD of the wheel and the ID of your axle, along with seals and custom spacers

Bearing swap would be the right way to do it.

You should be able to find the bearing number and related dimensions.
I'm not certain right now what the axle sizes on the Templar are but you'll needing a bearing with an OD the same size as your hub bearing seat and an ID that matches the Templar axle. Same for the seals.
Went down this road years ago when I did a super moto conversion on a '79 XR500
